Topic: Toluene Test (Read 5120 times)

Well as promised I tested Toluene in my last tank of gas. I went to get the Toluene and the guy wanted to know what it was for, so I told him it was for my car… It will strip of car paint? He said. No, it is for the fuel tank of my car. I got a really odd look and he did not ask any more…

I poured ½ gallon of Toluene into 8 gallons of 91. This created a 92.3 octane mixture. Noting too extreme, but it should be enough to tell if a gain is to be made.

It took about 8-10 miles of driving to feel anything (I needed to get the mixed fuel into the system) and then it hit me. The engine settled down, the smell of the car – I had the vents open – was different, and the throttle response was quicker. As I drove the car for the rest of the weekend, I was looking for additional differences and hopefully gains.

I tool a little trip to Colorado Springs on Sunday and I ran the AC the whole way home. I noticed that the car did not stumble or have throttle response issues – like it normally does – when I wanted to get into the gas with the AC running. I attribute this to the Toluene improving the combustion of the fuel and the timing not suffering retard due to pour fuel combustion and the AC sucking power.

I can say, without a doubt that Toluene in the tank makes a sizable difference (even in the low concentration I had) for daily driving. The power is smoother, the throttle response is not delayed, and the engine as a whole runs quieter and more efficient.

A patient of mine who is a mechanic said that ALL gas used to have Toluene in it, not exactly sure why they stopped using it, but his guess is that it is more toxic (can be absorbed into the skin he said?) and something about polution / emissions... I have no clue if there are any good or bad long term effects, maybe ask on Club B5 (there apparently is some wizzard gal there that knows a lot of about technical chemical stuff like this!).

If it does have an effect on emissions than probably need to have the car run for a month or so without it or it won't pass. And then there's those random emissions tests the city sets up like police check points.

He says that he feels like the engine gets dependent after a while, when he dosent mix it as hot or just puts pump gas in it dosent feel right to him. Not that it dosent run well or any thing like that, but it is deffinately not the same. He says that his puffs some thick black smoke from time to time, but its a DSM and is to be expected.

And he has been running a similar mix for as long as the car has been built, like 2 years now.

Reviving the topic since I stumbled across it and it seemed extremely useful [either to use or avoid]. SO! Anyone found what the side effects of mixing toulenewekjlsdkf into your gasoline? I'd be very curious to know and very anxious to try it out if the risk factor is extremely low.

I have gotten similar results. After 2-3 days of driving my Jeep(lots of mods) on 91 octain I realize that it is not running very smooth, poor throttle response, slow acceleration etc.

Before leaving the house in the morning I mix in 100% "Audi Key" in my pocket. The difference is noticable right away. Throttle response is back, smooth acceleration, ah hell....it has acceleration. :wink:

Okay, to stay back on topic. How does this compare in price to just mixing in a few gallons of 100 octain fuel? (or higher). There is a 100oct pump about 4 blocks from my office. (about $4.50 per gallon 8O )

Cole, there's a good article about Toluene in one of the last two European Car mags. Very detailed discussion. In summary, it says toluene is good, but is not designed to be added to a car in the form some of us buy it in. I don't remember specifics, but I do know there are advantages of buying 100 octane instead of toluene. I'm going to stick with the 100 octane instead of toluene.

The only long term effects that I have heard of is that the toluene breaks up and makes rubber bushings and seals brittle. If it is true, this only happens when the vehicle has the fluid in the tank for long periods of time.

Don't quote me on this information, I haven't done the research to back this info up and am just posting because this is what I have heard.

If anybody knows for sure, please let me know. We were running toluene at the track last year, and N/A motors really gain from this additive!!

I've used the T juice on and off for a while. The last track day event I attended I had a whole gallon of it mixed into about 3/4 of a tank of gas. the car ran real well that day a for a few days afterwards. It does work. But ever since I found a gas station near my house that sells 93 octane gas cheaper than most places sell 91, I've been fillimg my tank with that and not messing with the Toluene. Besides the cost in dollars there is the health issues to think about. Toluene is very, very toxic. Don't breath it, touch it or even look at it for too long. It's really bad stuff around human tissues. When I would pour it into my tank I did it out in the street wearing long rubber gloves, goggles and wearing a respirator. Don't take chances with this stuff.

And the reason the people at the paint stores give you a hard time when you go to buy it: some idiots use it to make meth anphetamines. These idiots acctually put this chemical mess into their bodies. Darwin was right.

But once it's safely mixed into your tank it's all good! VRAROOOM!!!!

Actually toluene is not used to make amphetamines, ether is, but toluene is used by some to get high. Huffing. They inhale it, go figure, at least they have no oil deposits or old paint anywhere in their bodies, that's for sure.

Toluene is a carcinogen but Chas, you can relax a little. You won't get cancer if you get in contact once in a blue moon. So wearing rubber suit aand a gas mask is really not required.
